Kawasaki DFI is only running in the emergency program.

Hello Have a problem with my Kawasaki. When driving ca2km it starts to ruckel and runs unround that takes about 40 seconds then the ECU switches to emergency program. ECU points to engine temperature sensor. Now I changed this problem remains. ECU changes the same What could it still be??. Motorcycle Kawasaki 1100 GPZ uniTrack Built 1984. I heard that this problem is only known it was never found. It was told me to expand this and build on gas It’s the only thing that didn’t help me. As much as I know there’s a Bosch injection system installed. Who knows there’s advice. It cost me something to restore it. now I can’t drive it.
